LAB 4: KIRCHHOFF’S RULES DIY Lab This section is adapted from reference 1. Objective In this experiment‚ you will experimentally verify Kirchhoff’s rules by measurement and by mathematical analysis. Apparatus (Lab Kit* or NIC Lab) 5 resistors one 6V battery or power supply (each under 1.5 kΩ each‚ not all equal) digital multimeter 12 connecting wires *If you do not have the Lab Kit‚ you can use equivalent items. Contact your instructor regarding equivalent items to ensure that the objective

emerged for drugs‚ meaning they affect only bacteria and not humans. Sulfa drugs‚ being antibiotics‚ allow bacteria develop resistance over time‚ meaning they stop to work after enough use. For this reason‚ sulfa drugs are typically used with another type of drug‚ trimethoprim. Together‚ these drugs block two enzymes and greatly reduce the probability of bacteria developing resistance to the drugs making them much more effective and useful. This subject interests me because it combines two of

There were a number of ways that resistance was made against slavery. They were: intellectual‚ direct/physical‚ and cultural. Examples of these types of resistance are portrayed throughout the narrative of Fredrick Douglass. This essay will discuss the three types of resistance citing examples from the narrative of Fredrick Douglas. Such examples of resistances were effective and meaningful in different ways and ultimately contributed to the acknowledgment and recognition of the poor treatment

stop‚ one would need to collide with something. In short‚ one would need some mechanism like rockets have to control motion. A larger problem would be that the threat of meteorites would be multiplied immensely (Goulding). Since there would be no resistance as the meteorite entered Earths atmosphere‚ even small meteorites would be able to penetrate our atmosphere and cause immense damage (Goulding). The damage a large meteor would cause would be catastrophic. Several ramifications that probably dont

the voltage source is equal to 0V‚ both the voltage and the current should be 0V and 0mA respectively which will make the plot go through the origin; however‚ because of the resistance from the voltmeter‚ the actual readings of voltage and the current when measured are a bit off from 0V(0.19V) and 0mA(0.09mA). -Unknown resistance (actual given value is equal to 2.2 kΩ) is the slope of the linear line of the graph‚ R ≈ 2.169kΩ Lee 3 Ohm’s Law (part II) R = 2.2kΩ Figure 1.2 Table 1.2 Vs I -10V

Antibiotics that are fed to cattle have been tied to the drug-resistances of salmonella which is found in humans. B. In his 2008 article “Antibiotic Resistance” in the Genetics Encyclopedia‚ Paul K. Small cited that the use of antibiotics in animal feeding is associated with antibiotic- resistant strains of bacteria. (Transition: However‚ there are other ways
